            int  currentrowposition = CurrentCell.RowIndex; // it must stay here
           int currentcolumnposition = CurrentCell.ColumnIndex; // it must stay here 
            if (keyData == Keys.Enter)
            {
                this.CommitEdit(DataGridViewDataErrorContexts.Commit);
                this.EndEdit();
                if(currentcolumnposition ==0 && string.IsNullOrEmpty(this.CurrentCell.Value?.ToString()))
                {                    
                    this.Rows.RemoveAt(currentrowposition);
                    this.SelectNextControl(this, true, true, true, true);

Hi @rahul kumar , Welcome to Microsoft Q&A.

As the error says, Uncommitted new row cannot be deleted..

Here you can use the AllowUserToAddRows property, set to false.

If you need to add it again, change it to true.

if (currentcolumnposition == 0 && string.IsNullOrEmpty(this.CurrentCell.Value?.ToString()))
{
    //this.Rows.RemoveAt(currentrowposition);
    this.AllowUserToAddRows = false;
    this.SelectNextControl(this, true, true, true, true);

    return true;
}

Best Regards,
